Generally, you will not be put completely to sleep. Almost all procedures require that you be given local anesthesia at the site of entry into the skin. For some procedures, the radiology nurse may give you medicine to help you relax. You may be drowsy, but you will remain conscious and able to speak and follow directions throughout your procedure. Your blood pressure, blood oxygen level, heart rhythm and breathing rate will be continually monitored throughout the procedure. Our goal is for you to remain comfortable and relaxed.
